生成图片

curl -X POST https://api.eggapi.ai/v1/generate \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "nanobanana",
    "prompt": "A clean editorial photo of a lemon tart on a steel table",
    "aspect_ratio": "16:9",
    "num_outputs": 1
  }'

import requests

response = requests.post(
    "https://api.eggapi.ai/v1/generate",
    headers={"Authorization": "Bearer YOUR_API_KEY"},
    json={
        "model": "nanobanana",
        "prompt": "A clean editorial photo of a lemon tart on a steel table",
        "aspect_ratio": "16:9",
        "num_outputs": 1,
    },
)

task = response.json()["data"]
print(task["id"])

const response = await fetch("https://api.eggapi.ai/v1/generate", {
  method: "POST",
  headers: {
    "Authorization": "Bearer YOUR_API_KEY",
    "Content-Type": "application/json"
  },
  body: JSON.stringify({
    model: "nanobanana",
    prompt: "A clean editorial photo of a lemon tart on a steel table",
    aspect_ratio: "16:9",
    num_outputs: 1
  })
});

const { data: task } = await response.json();
console.log(task.id);

响应：

{
  "data": {
    "id": "gen_abc123def456",
    "status": "pending",
    "model": "nanobanana",
    "type": "image_generate",
    "cost": "$0.00",
    "created_at": "2026-05-08T10:30:00Z"
  },
  "error": null
}

继续使用 GET /v1/tasks/{id} 轮询最终输出。

  -H "Content-Type: application/json" \
  -d '{
    "model": "nanobanana",
    "prompt": "Replace the background with a quiet marble kitchen",
    "image_urls": ["https://example.com/input.png"]
  }'

响应：

{
  "data": {

    "model": "nanobanana",
    "type": "image_edit",
    "cost": "$0.00",
    "created_at": "2026-05-08T10:30:00Z"
  },
  "error": null
}
